10 Biggest Behind-The-Scenes Fights From The Making Of Famous Movies

9. Sylvester Stallone Vs. Tony Bellew (Creed)

Although film sets have certainly changed since Sly first stepped foot onto one to shoot the original Rocky, one thing has not changed: Stallone will not tolerate any form of bullsh*t from anyone. So when TMZ reported that a very real fight had broken out during the middle of a scene between professional boxer Tony Bellew (who plays Adonis Creed's adversary, "Pretty" Ricky Conlan) and the actor playing his corner coach, the veteran action star had to step in to "clear things up." Most sources claimed that Bellew jumped out of the ring and started unloading on the other actor, while one claims it was simply a heated argument, and that no punches were actually thrown. I'm going to go with the consensus here and say that, at the bare minimum, some passionate pushing and shoving went down. Also, the image of a septuagenarian getting in between a couple of young bucks and restoring order is much cooler than one of Sly simply yelling across the room to "shut up and quit yer arguin'."
